Mitosis

Question 1

interphase

Answer 1

• 1st phase
• prepares for division by replicating its genetic and cytoplasmic material
• can be further divided in G1, S, and G2

Question 2

prophase

Answer 2

• 2nd phase
• chromatin thickens into chromosomes and the nuclear membrane begins to disintegrate
• pairs of centrioles move to opposite sides of the cell and spindle fibers begin to form

Question 3

metaphase

• 3rd phase

- spindles move to center of the cell and chromosomes pairs align along the center of the spindle structure

Question 4

anaphase

Answer 4

• 4th phase

- pairs of chromosomes, called sisters, begin to pull apart, and may bend

Question 5

telophase

Answer 5

• 5th phase

spindle disintegrates, the nuclear membranes reform, and chromosome revert to chromatin

• Animal: membrane pinched
• Plant: new cell wall form

Question 6

cytokineses

Answer 6

• 6th phase
